To all whom it may concern:

. Be it known that 1, ED FULLER, a citizen of the United States, residing at Elmer, in thecounty of Jackson and State of Oklaho1na,haveinvented a new and useful Axle- Box. for Locomotive-Drivers, of whichthe following is a specification This invention relatesto journal boxes of that'type especially designed for use in con nection with the axles of the driving Wheels of locomotives.

The object of. the

invention is to so inrprove the construction of devices of this,

- of the loooinotivefrdme.

' With these and other objects in view the inventionconsists of certain novel details of construction and combinations of-parts hereinafter more fully described and pointed out in. the claim.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings :-Figure 1 is aview partly in elevation and partly in section of the device constituting the present inven tion. Fig. 2 is a section on line AB Fig. 1.

Fig. 3 is a transverse section through thetie bar and showing the lower portion of, the Wedge and its adjusting screw in elevation. Referring to the figuresby characters of reference 1 designates. a portion of a locomothe hanger 2 and constituting a bearing tive frame and extending downwardly from this frame are hangers 2 and 3, the inner face 3 of hanger 3 being inclined upwardly toward for an adjusting wedge 4. which, as shown espec'ially in Fig. 3, has a groove 5 in one face at the lower end thereof. The upper end of this groove 13 enlarged as indicated at 6 to receive the round head 7 of an adjusting screw 8.

This screw rests within the groow e and the threaded portion thereof extends through and engagesn tie-bar 9 having transverse recesses 10 in its upper face into which the lower ends of the hangers '2 andB project. iach of these hangers has one or more grooves 11 in one face thereof, the upper ends of the grooves being enlargi-id as shown at 1.2 to receive the heads of fastening bolts 13. These bolts extend through the tie-bar 9 and are secured in place by means of nuts as ordinarily. Obviously by tightening the nuts on the bolts 13 the tiebar 9 can be firmly pressed against the lower ends of the hangers,end a rigid support thus provided for the axle-box.

As shown in Figs. 1 and 2 a locknut 14 may be mounted on the threaded portion of the bolt 8 so as to bear against the lower face of the tie-bar 9, and,'in order to permit this bolt to be readily rotated, the lower end thereof is reduced to form a head 15st) she ed as to be easily'engaged by. a wrench or ot 'ier suitable tool for the bolt.

Arranged above the tie-bar 9 and between the hangers Zand 3, are shoes 16, each of which is provided along opposite edges with longitudinal flanges 17. One of the shoes is purpose of turning the other shoe embraces the upper portion of the hanger 3 and the wedge l. These shoes. are held against longitudinal displacement by the frame 1 and thetie-bar 9, and arranged to slide between the shoes is a box 18 the sides of which are channeled longitudinal y as indicated. at 19 to receive the shoes 1.6. The box 19 has an opening .20 extending therethrough forsthereception of the axle and the bottom portion of this opening is formed by a cup .21 p which is removably mounted within the bottom portion of the boxand extends throughout the length of =the openingQO, said cup being held in lace by means of transversely extending hoxling pins 22, which are insertible laterally through the lower portion of the box adjacent the innor and outer faces thereof. The cup 21 is designed to hold waste or other similar material, and, as shown in Fig. l, a lubricant rcceptacle 23 may be formed in the upper portion of the box 18 and connnunicate with the opening 20 through. one or more apertures 24. l i

'Wedges have heretofore been used in connection with the boxes of itlriving wheels, but difficulty has been found in unseating them,

especially after-they have been in frictional designed to straddle the hunger 2 while the in a stuck Wedge, burned out brass, etc. It has also been diflicult to draw thewedge downwardly out of frictional engagement with the bearing surfaces because 'ot' the lack of proper connection between the bolt and the wedge. By roviding the shoe 16 between the box. and the Wedge 4 the bolt of the wedge is relieved of allstrains and the objectionab'le features heretofore enur rierated are thus entirely overcome. In View of'the par-' ticular connection employed between the bolt 8 and the wedge 4 said wedge can be shifted upwardly by turning the bolt in one direction, andcan be positively drawn downwardly by turning the bolt in the other direction. 1

The present invention can be applied to l0- comotives now in use without difiiculty and at comparatively small cost.

Obviously various changes may be made in the construction and arrangement of the parts without departing from the spirit or sacrificing the advantages of the invention.

What is claimed is:

In a device of the class described, a frame, hangers depending therefrom, a tie-barhaving grooves constituting seats for the endsof the hangers, tie-bolts detachably seated within the lower ends of the hangers and extending through the seats and the end portions of the tie-bar for helding the bar and hangerstogether, a wedge bearing against one of the hangers, said hanger having an in clined face, there being a countenbored recess within one end of the wedge, an adjusti'ng bolt removably mounted within said. recess, said bolt having a head nrovably mounted in the counterbored portion of the recess, said bolt being screwed into the tiebar, a shoe embracing the wedge and a portion of the adjoining hanger, a shoe ernbrac ing the other hanger, both shoes bearing upon the tie-bar, and a box interposed b tween the shoes and having seats or grooves in the sides thereof for the reception of the shoes.

In testimony that I clann the foregoing as my own, I have hereto afiixed my signature 1n the presence of two witnesses.
